Gasoline additives
Appl ies to vehicles: with gaso line engine
A major concern among many auto manufactur
ers is carbon deposit build-up caused by the type
of gasoline yo u use.
Although gasoline grades differ from one manu
facture r to another, they have certa in things in
common. A ll gasoline grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake va lves. A l
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas
oline. For more information on TOP TIER Deter
gent Gasoline, please go to the official website
(www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your en
gine of peak performance .
CD Note
-Damage or malf u nction due to poor fuel
quality is not covered by the Audi New Vehi
cle Limited Warranty.
- Do not add aftermarket fuel additive prod
ucts to your fuel tank.
Diesel fuel
Applies to veh icles: with d iesel e ng in e
Always use ULSD (Ultra Low Sulfur Diesel) No. 2.
The ULSD No. 2 meets the ASTM O97S.
Diesel fuel with concentrat ions of biodiesel high
er than S
% such as B11, B2O or B1OO are strictly
prohibited.
Service station fuel pumps are labeled w ith the
correct fuel information for easy recognition by
the user .
If the diesel fuel pump is not labeled
ask the station operator what fuel is being d is
pensed before filling up your vehicle.
ULSD No. 2 may not be ava ilab le outside the USA
and Canada. Be sure to check before traveling to
other countries .
Fuel and Refueling
ULSD No. 2 can become thicker in very cold tem
peratures, and this can impair the engine's start
ing and running. Depend ing on the season, gas
stations provide ULSD No. 2 that flows better in cold temperatures so that you can cont inue oper
ating your vehicle as usual.
CD Note
- Your vehicle's diesel engine was designed
soley for use w ith ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severe ly damage the fuel system
and the engine. Such damage will not be
covered by your New Vehicle Limited War
ranty.
- If you put any amount of incorrect fuel in
the fuel tank, do not start the engine under
any circumstances. Immediately contact the
nearest authorized Audi dealer or author
ized Aud i Service Facility for assistance .
These fuels contain substances that can se
vere ly damage the fuel system and the en
gine if the engine is started.
Refueling
Fuel filler neck
The fue l filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power lock ing system should fail, you can
still open the flap manually -for detailed instruc
tions see
¢ page 217.
You can find the fuel tank capacity of your vehicle
in
¢ page 278.
The label on the inside of the fuel f iller flap tells
you the correct fuel for your veh icle. For more in
formation about fuel specifications, see
¢page 213.
Your vehicle fuel tank has an on-board refuelling
vapor recovery system. This feature helps to pre
ven t fu el vapors from escap ing from the tank and
polluting the environment while yo u refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully .

Static electricity can cause sparks that can ignite fuel vapors released during refueling.
- Never smoke or have an open flame any
where in or near your vehicle when refueling or filling a portable fuel container.
- For your safety, we strong ly recommend
that you do not travel with a portable fuel
container in your vehicle. The container, full
or empty may leak and could cause a fire,
especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container whi le it
is anywhere in or on the vehicle (for exam
ple, in the luggage compartment, or on
the trunk). Static electricity can bui ld up

Fu el a nd R efu elin g
because f uel may spill out. In addition, the
expansion space in the fuel tank will be fi lled -
causing the fue l to overflow when it becomes
warm and pollute the environment.
@ Tips
- Running your engine whi le refue lling may
cause vapors to escape or even cause fue l to
spill out of the tank. This would then sh ut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition turned on. The fuel gauge may otherwise not indicate the correct fuel level after refu
elling .
- Diesel vehicles* are equipped with a diesel
m isfueling protector .
It allows the vehicle to
be fueled only with a d iesel fue l pump noz
zle . A wo rn o r damaged nozzle o r a nozz le
that is too small may not be able to open
the diesel misfueling protector.
If this is the
case , try turning the nozzle before insert ing
it in the fuel filler neck, use a different fuel
pump or see your authorized A udi dealer or
authorized repair facility for assistance.
- The fuel fi ller f lap of your vehicle is not
locked when you lock the vehicle from the
